MACHINE GUN.

Application :filed January 24, 1927.

The invention relates to machine guns. The object of the invention is toconstruct and provide a machine gun which will shoot without use ofpowder or the like. A further object of the invention is to provide amachine gun, the bullets whereof will not be inserted in cartridges.containing powder or other explosives. A stillfurther object Yof theinvention is to provide a'niachine gun .0 the use whereof will beconnected with com-p paratively little noise of explosion.

Other objects not specifically mentioned will be easily ascertained andunderstood from the following specification in connection. with thedrawings forming a part thereof;

In the drawings showing a preferred embodiment of the invention Figure 1isa side lview of a machine gun according to the invention. Figure 2 isa central vertical longitudinal section through said machine gun. Figure3 is a section on line 3-3 of Figure 2. Figure 4 is a section on line 44 of Figure 2, and Figure 5 is a section on line 5 5 of Figure 2. A gunbarrel 6 is screwed intothe wall of an explosion chamber 7 of Vaninternal combustion engine the body 8 of said combustion engine to whichthe co1nbustion chamber isV fastened contains a cylinder 9 and an intakechannel 10. The carburetor 11 is fastened on the end of the intake 10and communicates with a gas tank 12 fastened to and carried by theengine. Onto the free end of the cylinder 10 a housing 13 is fastenedand in said housing a crank shaft 14 is journaled. Connecting rod 15connects the crank of said shaft with i the piston 16 adapted toreciprocate in the cylinder 9. A valve 17 of the well known tappet typein the intake channel 10 prevents the gas from entering into thecombustion chamber 7 as when said valve is in closed position in theusual way. A gear 19is mounted on a prolongation 20 of the crank shaft14 and said gear meshes with a second gear 21 mounted upon a stud 22fastened into'the wall of the casing 13. A third gear 23 is mounted upona shaft 24 journaled in the walls of the casing 13 and extending throughsaid casing. A cam 25 is mounted upon the shaft 24 and is adapted toengage the upper end of a tappet rod 26 adapted to engage the end of thevalve stem 27 of the intake valve 17. The tappet rod .e5 26 is slidablymounted in sleeve 23 ferme Serial No. 163,135.

ing an integral part of the body casting of the engine and extends intothe interior of the casing 13 into the vicinity of cam 25. On the sameside of the casing on which the gears 19, 21 and 23 are' arranged,another gear 29 is mounted upon a shaft 30 also extending through thecasing 13 and journaled in the walls thereof. The shaft 30 is locatedunderneath the shaft 24 and extends parallel thereto. The gear 29 meshesalso with the gear 21. The cam 31 is mounted upon the shaft 3() andarranged inside the casing 13. l

A magazine 32 of the well known worm type adapted to contain bullets isdetachably fastened to the lower part of the combustion chamber 7adjacent the end of the barrel 6 screwed in the wall of the combustionchamber. As indicated in Figure 2the bullets 33 have the usual form ofrifle bullets, but are not inserted into cartridges. These bullets willbe fed by means of a spring 34 contained in the magazine in the usualway to the intake opening Vin the barrel. In order to regulate the feedof the bullets and in order to insert the bullet in position in front ofthe barrel into said barrel a push rod 35 is slidably supported by a lug36 on the cylinder wall. A spring 37 surrounds said push rod 35 andabuts with one of its ends the lug and with its other end a stop 38adjustably mounted on said push rod. A tappet rod 39 is slidably iountedin a lug 49 of the body of the en- `gine and is adapted to engage theend of the push rod 35. The other end of said tappet rod extends intothe casing 13 into the vicinity of thecam 31 and is adapted to bcactuated by said cam. l

On the other end of the push rod 35 a pin 41 is fastened carrying aplate 42 which is arranged in such a manner that. it is located directlyin front of the bore of the barrel 6. A slot 43 is provided in thccasing of the combustion chamber 7 and the pin 41 eX- tends through saidslot and the plate 42 covers said slot. When the cam 31 permits the rod39 to slide into the casing 13. the spring 37 moves the rod 35 to theright in Figure 2. Thereby the pin 41 and the plate 42 is also movedtowards the right. A channel 44, provided in the casting of thecoinbustion chamber and forming according to Figure 2, a prolongation ofthe channel in the 32. will be imeavered that a,

bullet Willbe brought into position in front of the bore of the barrel6'.y rEhe movement of the cam 31 is timed in suoli a manner, that assoon as a bullet is brought into this po-y sition, the cam Willforce-thev tappet roch 39'-y and thereby the push rod 35 to the left inFigure 2 whereby the plate .42 will force the bullet located in front ofthe barrel intoY the bore thereof and Will' at the same time pref ventthe other bullets from. being forced into the; explosion chamber. n

A.. sparkplugj 45 is.v insertedy in4 the Wallil ot the;combustionchamber 7 in the vicinity of the. outlet of the antic channel10. Anelectric: conductor 46. connects said sparkplug mounted and. a.handle 49 may bel fastened to said Viiy Wheel; I

Vfhen the y Wheel isk rotated the piston Will. be,V reciprocated, in thecylinder 9., and

at the samev time the cam will be rotated ters of Patentsy is:

f since the gear 14 will rotate with. the fly ,Wheel 48 and Will actuatethe gear 23 by means ofthe gear 21. Seeing that the gear 291salsofmeshing with the gear 211, the push rod will be also actuated byrotating the yfly Wheel 48 and the timer 47 will time the explosions. i

'1n order to prevent an accidentaliring a lock. 49 is provided whichsecures.l the pnshi rodf35 from; accidental movementi thel lever 50 inanotch 53 provided in the` vpush rod 35. As long as the upper portionkof the lever 50 is in engagement with said barrel 6. By pressing on thelower portion of .the lever 50 the rod 35 becomes free for movement andwhen the fly vvheel is rotated either by hand or by the movement of thet piston in the cylinder, the cam 31 Willac'- tuate the push rod so thata'bullet may bev fitted into the barrel The explosiony of the gases inthe combustion chamberv 7' will take the place of theV exploding powdervin f a cartridge and Will drive the bullets tlnoiigh the, barrel.

From the above it vv-ill. be understood that the engine may be runWithout any bullets being fired. Then the push rod 35 is sc- A lever 50is pivotally mounted on the lug,y 36 at 51," vandv a spring` 52forces'the upper portion of cured by means ofthe lock lever in theposit'iony shown in Figure 2, the cam 31 may rotate Without actuatingsaid rod and the spring 37 is prevented from moving said rod` towardlthe cam. In this manner it. is pos` said lever 50 against the rod 35 andas soon as the notch'A 53'V will come in registration with the; notchyin the lever, said lever-'Will engage said notch and lock the push rod'35 rsible to fire a single shot by pressing on the `lower part of thelever 50 and then release and secure it against movement. The Whole K yan electric, connection 58 leads toa battery not, shown and a second`connectionf59 leads fromv the batteryv to the. body of the casing 13 to,close the circuit., f
